OIL-CAN.

SPECIFICATION forming part of Letters Patent No. 496,246, dated April25, 1893.

Application filed August 8, 1892.

Be it known that I, JAMES A. CAMPBELL, of New Orleans, in the parish ofOrleans and State of Louisiana, have invented a new and Improved.Oil-Can, of which the following is a specification, reference being hadto the an nexed drawings, forming apart thereof, in which- 7 Figure 1represents a vertical, central sec tion of an oil-can embodying myinvention. Fig. 2 represents a vertical, central section of the canat'right, angles to that shown in Fig.

1. Figs. 3, 4, and 5 represent perspective views of detail portions ofthe device, and Fig. 6, a central vertical section of the nozzle mouth-'piece. v

The object of my invention is to provide an oil can, simplein-construction, economical in manufacture and durable in character; andin which the discharge valve will normally remain closed when the bottomof the can is not pressed.

It also has for its object means for regulating the flow of oiltherefrom and other means to prevent the waste of any drip that mayremain on the wire, outside of the nozzle, after the oiling has beenaccomplished.

For these purposes, my invention consists of an oil-can constructed ashereinafter set forth and pointed out in this specification.

A designates the body of an oil-can, the walls of which are of anysuitable shape and material, and the bottom B of flexible materialforming a diaphragm.

C designates a nozzle having at its lower end an exterior screw threadfitting on ascrew thread on the body A. A flange D on the lower end ofthe nozzle above the screw thread, serves to limit the downward motionof the nozzle in securing the same to the body A. Between the saidflange and the flaring upper portion O of the threaded portion of thebody is the gasket E, wherebyaclose joint is made, thus preventing anyescape of oil at this place. The upper end of the nozzle is flaring, asat F, for the purpose hereinafter described, and

is formed of a double cup shape piece, as in Fig. 6, having a connectingneck F within which the wire G is guided. The lower cup or socket E isof such diameter as to receive the upper end of the conical portion ofthe Serial No. 442.522- (No model.)

I nozzle, leaving a space between the latter and the wire G. Within thenozzle and body of the can is the wire G, the upper end ofwhich is bentor curved, and vtapering in form and projecting beyond the nozzle. Onone side of the upper end of the said wire G is a cutaway or recessportion H, of greater length than the neck F of the mouth piece. Thewire G is of such thickness that it normally closes the neck F above theraid recess portion H; but when the wire is raised by means of pressureupon the flexible bottom B, the recess H is brought upward so as to formapassage between the inner wall of the neck and the wall of the recess,whereby, when the can is tilted or inverted, oil may flow therefrom andbe guided through said passage, on the curved end of the wire G to theplace of deposit. It will be seen that the flaring edge of the upper endof the nozzle reliably guides the drip on the end of the wire G backinto the can.

To keep, and also adjust, the wire G in proper position in the can, andto return the flexible body B to its normal position, the followingmeans are employed: Secured to the bottom of the wire G, is an adjustingpieceJ formed of a piece of metal having a screw threaded socket Ktherein in which a threaded portionof the wire G is secured. It will beseen that by this threaded connection of the piece and wire, adjustmentsmaybe made to compensate for different lengths of wire and for wear ofthe different parts, so that at all times the position as well as thesize of the valve or opening at the mouth of the nozzle may beregulated. A guide piece L, consisting of a strip of metal bent as shownin Fig. 5, is tightly secured in any suitable manner in the lower end ofthe nozzle; and through an opening M in the cross-bar of the same isguided the wire G in its movements. Encircling the said wire G, andbearing against the under side of the cross bar of the guiding piece,and the upper end of the adjusting piece J, is a coil spring N, whereby,when pressure is removed from the flexible bottom B, the said adjustingpieceJ with the wire Gis forced downward so that the upper edge of therecess H is brought below the top edge of the neck F" of the nozzle, andthe opening through which the oil escapes is thereby closed. The

guiding piece L is preferably formed of a piece of sheet metal bent intoform so as to have its sides adapted to bear against the inner faces ofthe nozzle, and to have the limbs or flanges P on the lower end of thesides, to abutor be in contact with the lower edge of the nozzle,whereby a firm and reliable connection between the said guiding piece Land the said nozzle is efiected without the aid of any solderingwhatever. The adjusting pieceJ may also readily be formed of a thinpiece of sheetmetal doubled so as to form a socket portion in which thewire G may be adjusted.

It will be seen i hat, as constructed, the parts are few in number,easily and cheaply made, and not liable readily to get out of repair,and at the same time furnishing a device from which oil can be readilytaken when desired, and one in which the drip usually remaining on theoutside and end of the wire,is prevented from escaping to the outerportion of the nozzle, but is safely guided so as to re-enter the can.

I am aware that in a former patent of mine No. 411,977 of date October1, 1889, there was shown and described an oil can in some respectssimilar to the one shown in this application, but in the oil can in saidpatent the end of the wire was not tapering, neither was the upper endof the mouth-piece of the nozzle flaring, nor was the guiding pieceformed as the one herein described and held by lips against the loweredge of the nozzle, nor was the adjusting piece formed as in this case.

These diiferences, while apparently small, are of practical importancein the eflicient operation of the device as well as in lessening thecost of production.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In an oil can, the combination of a nozzle and a guide piece formedof asingle piece of spring metal having lips at its lower end abuttingagainst the lower edge of the nozzle, and a wire passing through anopening in said guide piece.

2. An oil can having a nozzle with a mouth piece formed of upper andlower cups with connecting neck, said upper cup having fiaring sides andsaid lower cup adapted to embrace the upper end of said nozzle, and aguide wire closely fitting in said neck, said guide wire having a curvedtapering end, said parts being combined substantially as described.

3. An oil can having a flexible bottom, an adjusting piece formed of asingle piece of sheet metal bent into form and having a socket at ornear the central line thereof and extending to the lower end thereof, aguide wire adjustable in said socket, and a tapering nozzle with upperflaring end, said guide wire having a tapering upper end, said partsbeing combined substantially as described.
